PLP-Series Air-Trap™: Positive Pressure, Low-profile - Pressures from 0 to 40" WC HVAC Waterless Condensate Trap

Problem solved

We wanted neither a pump nor a regular p-trap that could dry up when the unit is not being used much. The air trap met that need and, so far, has worked beautifully.

Fast Shipping!

Trap is moderately priced and shipping was very fast! Excited to see trap functionality very soon.

Works great

My condensate drain is on the positive pressure side of evaporator coil and was blowing air cold air into attic through 3/4" PVC drain line. Installed PLP trap in drain line, it now drains condensate with no cold air loss. Easy to install. Only downside is that it is a little pricey
